Member action popup

So I wanted to do for my company's webpage, a thing where are links that belong to people, to make it when you click, you have a little menu where you can choose to send him a message or view his profile..
Before click:
After click:
I tryed to search for it, couldn't find anything of much valuable.. Maybe someone can help me out.

If you're looking for an easy way to do it, I recommend using jQuery (http://jquery.com/) with one of the popup plugins (http://plugins.jquery.com/tag/popup/). It's easy to install, and most of them have a working demo for you to test out before download.
Otherwise, coding a popup window with pure JS takes time.
This general method is to:
Create a hidden div
Position: absolute and play with the z-index so your div will be on top of all other elements.
Set the position to where you clicked, or somewhere around the area of the target.
Take into account the width and height of the window/screen. (i.e. No poing in showing a div that'll appear off screen).
Fill it in with information you need.
Make it appear.

The way I've done things like that in the past is to have a hidden absolute or fixed DIV layer that houses that message menu. Then have a click trigger make that div layer visible and positioned at the current mouse coordinates.
There should be a lot of articles on google telling you how to do the various stages of all those steps.

Tool Tip jQuery to appear outside slide element

I have a jQuery conundrum that I'm not sure can be resolved. Inside a content slider I have absolutely positioned divs creating a tool-tip style pop-up on hover. Because the containing content slider overflow must be set to hidden, the tool-tip pop-up gets cut off where it overflows. I would like the pop-up to display in full when overlapping the slider it is contained within. If anyone has a workaround for this I'd be very appreciative!
Here's a link to my working file from which you can see the problem and the code.
Many thanks for any advice.

Your animation inside 'slidesContainer' relies on overflow:hidden so the large image doesn't stick out of the div and the only way for you to get the balloons pop out is to remove that overflow:hidden and make it visible
I don't think you can have the two at the same time

Right, so I don't think there was a straight forward solution so what I did was change the script to refer to div IDs instead of referring to the 'next' div. I moved the pop-up div's outside the slide element and absolutely positioned them relative to the page rather than the link. It's more long winded but works fine! Just means you need to refer individually to each pop-up div in the script. Thanks for you help anyway!

Figuring out if overflow:auto would have been triggered on a div

// Major edit, sorry in bed with back pain, screwed up post
One of the ad agencies I code for had me set up an alternate scrolling solution because you know how designers hate things that just work but aren't beautiful.
The scrolling solution is applied to divs with overflow:hidden and uses jQuery's scrollTo(). It's a set of buttons top and bottom that handle moving the content.
So, this is married in places to their CMS. What I have not been able to sort yet is how to hide the scrolling UI when overflow:auto would not have been triggered by the CMS content and the buttons are not needed.
The divs have set heights and widths. Can i detect hidden content? Or measure the div contents' height?
Any ideas?

So you want to get the height of a hidden element? I found this post maybe it is what you are looking for.
Its using jQuery, but the concept is the same. Hope this helps!

I hope i am mistaken, but you would need to emulate overflow by setting properties using some js, then you can get these values using getAttribute or your own method. Otherwise when you set overflow to auto, then the browser will be doing its own thing and the only value returned as a property of overflow would be a string like 'auto'.

Can you explain this better? You want to hide the scrollbar of a div set to overflow:auto when it doesnt have enough text to overflow? Browser does this for you.
You want to hide the scrollbar of a div set to overflow auto when it is scrolled down to some point, but you arent looking at it or hovering or something? That will be sort of complicated.
If you want to know if a div has overflow set to something, you just do:
object.style.overflow
and it will give you a string.
possible values:
visible
hidden
scroll
auto
inherit
you can set overflow the same way

from what i understand now is you have these divs with hidden scroll, but some graphic designer custom scroll bar and you use scrollTo to do the actual scrolling. BUT you problem lies when you dont have enough data to actuall need a scrollbar, but your graphic stuff shows up anyway, so you want to hide it.
so the real question here is how do you get the height of content? you want the property offsetHeight, but im pretty sure its still IE only.

What do you mean by CMS?
Yes you can access the div's content height, since you can access all of the div's children in JavaScript. (Sorry for not including example. I haven't work with pure JS in a while now so I don't want to point you in the wrong direction.)
Doing this, you'll kind of be able to "detect hidden content" and then be able to do what you actually want to do.
About your first question, I doubt you can control scroll bars once you've set overflow to auto.

Using jQuery height() on a div containing the content I am able to show/hide the user interface as needed based on whether height exceeds the CSS height of the div with overflow:hidden.

Horizontally scrollable table column

I would need to build a html table that has a horizontally scrollable column. The scroll should be placed in the column's header.
My first question is: do you know any jQuery plug-in that is able to do this?
My second question: is this possible using a single table? I've heard that in order to do this you need to use multiple synchronized tables that look like a single one from the user's perspective.
Any idea/advice would be welcomed.

I've only seen something like this using jqGrid, but that was two tables (the master table has a second scrollable table within it). I'd like to know a plugin for this as well...

I would do as you suggested and use 2 containers. They'd both be set to overflow:scroll and have a set width, but the top one would simply contain a div that you can set to be the same width as your table. You can then bind to the "scroll" event in jquery, and set the scroll position of the divs to match each other in that event. Honestly I haven't tried this so I don't know how reliably that event fires, but in theory it should work.
Alternatively, you could do without the standard browser scrollbar and write your own scrollbar that uses javascript to set the position of your table in the overflow:scroll div. If you want draggable behavior (not just left/right arrows), it could be somewhat difficult, but wouldn't be impossible.

How to create modal dialog/pop up without title bar using javascript

Want to know How to create modal dialog/pop up without title bar using javascript which will work on both IE and FF.
Thanks.

You're going to have to make a div that sits--absolutely positioned--in the middle of the viewport (or wherever you want it) above all the other elements--using z-index. This is where your content goes. Now, I recommend a film to go behind it, but above everything else--again using z-index. Then place a handler on that film that places focus back on the "modal" div. Also, you might want to place a focus handler all the other elements (not the "modal" div), using event delegation, that places focus back on your "modal" div--just to be sure.
You also might want to look at how jQuery UI does it. You'd only need to remove the title bar from. In fact, you probably could just use that one and mess with the CSS to hide the title bar.

I do this with two divs. I lay one div over the whole screen and make it semi-transparent, then I lay my "popup" div in the center of the screen with a higher z-index. The popup div can then contain whatever content you want.
